Well you are wrong, Israel doesn't want the land. Most of the people I know in Gaza/West bank don't want to destroy Israel either. Infact everyone I know in Israel/Palestine wants peace, no need for walls, checkpoints so they can just live their lives.
Hamas fires rockets due to Gaza being a ghetto, so Israel bombs more rockets etc etc etc. The only way to get peace from what I've read, and heard from people on both sides is for the Israeli govt. to stop holding all the cards and give the Palestinians some control over their lives. They will never give Hamas any control even if elections were held that the Israelis oversaw. It doesn't help that the western leaders sit back and harp on about terrorists when a state is allowed to blow up who it wants. If hamas attacked a military target it would still be terrorism, so they can't win.
"David Miliband, said the escalation of the conflict would cause alarm and dismay." - This is from the beeb, seriously if you are going to say something, say something that has meaning . The French seem to be acting the best, but I think they said before the ground forces are a "defensive" move, so they all seem to be sitting in the s***.
As for 3/4 of the world. Maybe some leaders may not like it, but I'm sure most people on here don't hate Palestinians or Israeli's for that matter. Obviously Israel is going to be covered by the US at the UN, so the most likely way to resolve the conflict is going to be vetoed, maybe Obama will change the Israel "$3bn" aid thing but I doubt it.
This is an interesting article on the beeb -
